HATCHWAY-GUARD.

SPECIFICATION forming part of Letters Patent No. 228,925, dated June 15, 1880. Application filed April 15, 1880. (No model.)

To all whom it may concern Be it known that I, GEORGE PARKER, 0 Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Safety-Guards for Hatchways, of which the following is a full,

clear, and exact description.

This invention consists of a railing placed about or around either the whole or a part or parts of an open hatch or hoist way at a height above the same suitable to make a guard and protection against accidents to persons while the hatch or hoist way is open, and constructed in a manner, at one or more or all of its sides, to allow the free passage through it of the hoistingrope at all times, and to be opened, if necessary, for the passage of goods either to or from the open hatch or hoist way, all substantially as hereinafter described.

In the accompanying plate of drawings my improved safety-guard for hatch or hoist ways of buildings is illustrated.

Figure 1 is a plan view of an open batch or hoist way having my improved guard; Fig. 2, a side elevation; Fig. 3, a vertical section on line 00 00, Fig. 1.

In the drawings, A represents a floor of a building, and B an open batch or hoist way through the same; 0, a horizontal railing, which is supported by suitable posts D, and surrounds the open hatchway B. This railing 0 is at a suitable height above the open hatchway to guard and protect the same against the accidental passing of persons to it.

At one side, E, it is shown as constructed of two horizontal arms, F, which are in line with each other, and are hinged to the posts D to open outwardly from the hatch way, and when in line with each other to be firm and rigid against swinging or moving inwardly toward the opening of the hatchway.

G is an opening between the ends of the arms F, which are toward each other. This opening G is of sufficient width to allow the hoisting-rope to freely pass forward and backward through the same, and to facilitate the running and entering of the rope into the opening from the outside of the guard, each arm F on its outer and upper sides, a and b, as well as at its corner cl, being beveled or inclined toward the said opening, as shown in the drawings.

H is a spiral or coiled spring secured at one end to the swinging arm and at the other end to a suitable part of the fixed guard, and arranged to pull against the outward opening of the arms, and to automatically close the arms, after being so opened and upon their release, to the action of the springs.

Spring-hinges may be used for hinging the arms to the posts, in which case the springs H may be dispensed with; and, again, obviously, the arms may be provided in various ways with springs or elastic cushions to close them, as described.

In the drawings one arm is represented as operated by the spiral spring H, and the other by a spring-hinge, J.

The several sides of the rail or guard 0 may be provided with arms E E, as has been described.

A rail or guard having the character of construction hereinabove described obviouslyrenders the open hatch or hoisting way absolutely safe and secure against accidents to persons, while at the same time it offers no practical or substantial hinderance to the use of the hatchway for hoisting purposes.

The advantages and importance of such a rail or guard in cases of fire, &c., are so manifest that even a general reference to them is not necessary. I

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A rail or guard to a hatchway constructed to open outwardly, and to allow the hoisting-rope to pass through it when closed, all substantially as and for the purpose described.

2. A rail or guard, 0, having swinging arms F, arranged to open outwardly, and for the hoisting-rope to pass between their ends, all substantially as and for the purpose described.

3. A rail or guard, U, having swinging arms F, arranged to open outwardly, and for the hoisting-rope to pass between their ends, and constructed to guide and run the rope to the opening between said ends, all substantially as described, for the purpose specified.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

. GEORGE PARKER.
